Insights

Cyclin-dependent kinase 2 (CDK2) drives cell cycle progression and is linked to tumor growth. Selective CDK2 inhibitors show promise for cancer therapy, though a truly selective inhibitor remains elusive.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Cyclin-dependent kinase 2 (CDK2) regulates cell cycle progression through S- and M-phases.
  • While dispensable for normal development, CDK2 activity is implicated in the growth of various cancers.
  • The therapeutic potential of CDK2 inhibition in oncology is under investigation despite historical controversy.

Purpose of the Study:

  • To review the current understanding of CDK2's role in normal and cancerous cells.
  • To discuss pharmacophores utilized for CDK2 targeting.
  • To outline strategies for developing rational CDK2 inhibitor designs.

Main Methods:

  • Literature review of CDK2 function in cell cycle and cancer.
  • Analysis of existing small-molecule CDK2 inhibitors and their pharmacophores.
  • Discussion of rational drug design principles for kinase inhibitors.

Main Results:

  • CDK2 plays a critical role in tumorigenesis, making it a target for anticancer drug development.
  • Several small-molecule CDK2 inhibitors have advanced to clinical trials.
  • A major challenge remains the discovery of a highly selective CDK2 inhibitor.

Conclusions:

  • Selective CDK2 inhibition presents a potential therapeutic strategy for specific cancers.
  • Further research into rational design is needed to achieve CDK2 selectivity.
  • Targeting CDK2 may offer new therapeutic avenues in cancer treatment.

cAMP-dependent Protein Kinase Pathways01:25

cAMP-dependent Protein Kinase Pathways

Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Protein Kinases and Phosphatases

Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.
Protein kinases
Many proteins in the cell are regulated by phosphorylation, the addition of a phosphate group. A family of enzymes called kinases...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

Eukaryotic Transcription Inhibitors01:52

Eukaryotic Transcription Inhibitors

Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a...
